In 1995, he briefly appeared in the World Wrestling Federation as Xanta Klaus. At In Your House 5: Seasons Beatings in December, while Savio Vega and "Santa Claus" were at ringside handing out presents and playing to the fans, villainous manager "Million Dollar Man" Ted DiBiase appeared. DiBiase proclaimed that everyone had a price, even Santa. As Vega argued with DiBiase, "Santa" jumped him from behind and attacked him. DiBiase laughed his trademark laugh and introduced this warped Santa as Xanta Klaus, Santa's evil brother from the South Pole who steals presents. As Xanta, Rechner made only a couple more appearances (one on the following night's Monday Night Raw), before never being mentioned again.[5]

In 1997, Rechner signed with Extreme Championship Wrestling (ECW) and found success as Balls Mahoney. Capitalizing on the ECW crowd's lust for violence and the hardcore attitude Rechner was never seen without his signature steel chair, usually with some kind of writing or sign placed on it, which he would use to bash any opponent at any time. He would come to the ring to the AC/DC song "Big Balls" and lead the crowd in singing the chorus before or after his matches. While in ECW he teamed with Axl Rotten, a similar hardcore and violent wrestler, and the duo became informally known as "The Hardcore Chair Swingin' Freaks". They feuded with the Dudley Boyz (Buh Buh Ray and D-Von) during their tenure.

Mahoney's first singles match at a pay-per-view was a victory over Steve Corino at Living Dangerously.[15] Shortly after, Mahoney formed a tag team with Spike Dudley. At Hardcore Heaven, the two faced the Dudleyz in a championship match but failed to win the title.[16] The two teams faced in a rematch at Heat Wave, and this time, Mahoney and Dudley won the match and the ECW Tag Team Championship, marking Mahoney's second individual reign.[5][13][17] At a show in August, the duo lost the title back to the Dudleyz.[18] On the August 14 edition of ECW on TNN, they defeated the Dudleyz in another rematch to win back the ECW Tag Team Championship.[5][13][19]

During an exchange of blows, ECW fans would often chant "Balls!" when Rechner landed a punch or kick on an opponent, and "Nuts!" when his opponent retaliated. At Living Dangerously, he defeated Kintaro Kanemura.[23] He met his former tag team partner, Masato Tanaka in the first match at Hardcore Heaven, which Tanaka won.[24] At Heat Wave, he lost a match to F.B.I. member Sal E. Graziano.[25]

In 2006, when WWE relaunched ECW as their own brand, one of the first announcements was the signing of Balls Mahoney. His signing was announced with that of Axl Rotten, but when Rotten missed some WWE dates and was released, Balls was left to start a singles career. During the "cross promotion" hype, Balls appeared on the June 5 edition of Raw with other ECW wrestlers who proceeded to attack WWE ChampionJohn Cena.[32] He appeared again as a part of the ECW team in the "WWE vs. ECW team battle royal" at the WWE vs. ECW Head to Head event on June 7.[33] At One Night Stand, Balls defeated Masato Tanaka in a match following a chair shot (denting the chair) to Tanaka's head.[34]

When ECW on Sci Fi debuted, Balls started off with a small role in the company, having sporadic matches and little else. Once the show got going he started to appear in vignettes talking about how tough he was, elevating his role on the show. On the September 5 edition of ECW on Sci Fi Mahoney entered a feud with Kevin Thorn after Thorn and his valetAriel cost him a match against Stevie Richards and the next week, René Duprée.[35][36] The following week, he brought Francine to ringside with him, marking her first televised appearance at the revived ECW ring, where she proceeded to get into a catfight with Ariel.[37] That pairing, however, was short lived as Francine was released shortly after.

During and after the match, it appeared that Kelly Kelly was concerned about him.[5][41] Over the weeks that followed, he attempted to ask her out and flirted with her backstage, but was interrupted by The Miz, Brooke, and Layla before Kelly could get a word in. Regardless, Kelly still showed interest in him each week, wishing him good luck before his match and cheering him on during his match.[5] He asked if she would go out with him to which she could not respond due to The Miz taking her backstage.[5] Weeks later, however, Kelly asked him out, starting an on-screen relationship.[42]

On July 29, 2010, it was confirmed that Mahoney would take part in TNA's ECW reunion show Hardcore Justice on August 8.[47] However, his name was later pulled from the event's official website.[48] On August 8 it was revealed that this was done due to WWE owning the name Balls Mahoney. At the event Rechner, using the ring name Kahoneys, teamed with Axl Rotten in a South Philadelphia Street Fight, where they were defeated by Team 3D.[3] After the match Rechner vented his frustrations on Axl Rotten, proclaiming that he would never again team with him.[49]
